Lowrance HDS5 Gen2 Review

Lowrance HDS5 Gen2 has an average rating of 1.5 out of 5 based on 4 user reviews.



The Lowrance HDS5 Gen2 is a new model for 2012 and it is an improved version of the old HDS5. It features a more powerful processor which gives the fishfinder faster re-draws and quicker response to user input. It has more memory that its predecessor and that allows it store more TrackBack. But the main improvement is the StructureMap – a great feature that provides a way to overlay side-scan images on a map display. StructureMap is only available with the optional StructureScan module. The Lake Insight model variation also makes it possible for users to get a greater display inland and in freshwater mapping views. The Nautic Insight variation can cover the US coastal areas in greater detail. If the Lowrance HDS5 Gen2 is to be used internationally in Non-Americas locations the Navionics variation is the best suited option for potential buyers. The HDS5 Gen2 is compatible with a wide range of third party tools and hardware including Insight HD, Fishing Hot Spots Pro, Navionics Gold-Platinum with Turboview.

I have a few problems with my new Lowrance HDS5 Gen2:

– From time to time the GPS signal drops, seems that the internal GPS component is not as reliable as the puck I used with an older unit which never lost signal.
– the mount is not resistant to shaking. The original bracket that came with the unit broke and I had to replace it.
– I’m using the base maps and they are not accurate. I sometimes discover that my track goes across a land. I had this multiple times, it’s somewhat concerning.
– The user interface is not very user friend, it’s hard to understand the menus and you will have to spend a lot of time getting familiar with it.

After installing this fishfinder on my boat, I realized that my autopilot is malfunctioning. Later I realized the unit has a magnetic card door which affects compass and auto pilots. If you have a smaller dashboard like I do, you might want to reconsider buying this unit.

I’ve been using my HDS 5 Gen2 for a little over 2 years when it started malfunctioning, the screen would flicker, the GPS would cut out, it wouldn’t read the map card. Eventually the unit gave in completely. I thought I could get it fixed by the manufacturer, little did I know. They don’t fix these units, they want you to buy a new one. That’s right – they expect you to buy a new $600 fishfinder every couple years!

I was heading back in after a day on the water and suddenly the unit went completely dark. When I got back I check every connection and all fuses and power source. Still I got nothing from it. My experience with Lowrance was not much different. I stayed on the phone only to find out that it was just past the warranty and all they could suggest was purchasing a new unit. I will buy a new one just not form them.

Got my unit on a new boat in 2012. First trip in 2016 the sounder no longer functioned, couldn’t or would not find the depth. Trying to decide if it’s worth giving. I’m gessing not.
